You can find the latest version on the release page:
The mac bundles are not signed at the moment so you might face the following problems when opening the application:
If your mac is telling you that this app is from a unverified developer you can allow it via the "Privacy & Security" settings. More info: Open a Mac app from an unidentified developer
On M1, M2, etc. it can happen that the app is reported as damaged. Just copy Sales & Dungeons into your Applications folder and execute the following command to allow it to run:
xattr -d com.apple.quarantine "/Applications/Sales & Dungeons.app/"
The headless version of Sales & Dungeons (using LibUSB) is also available via a docker container:
-
docker pull ghcr.io/bigjk/snd:master
(container) -
docker run -p 7123:7123 --device=/dev/bus/usb --group-add uucp -v /some/place/to/persist:/app/userdata ghcr.io/bigjk/snd:master
- change
/some/place/to/persist
to a folder where the user data should be persisted to - replace
/dev/bus/usb
with the device of your usb/serial printer - replace
uucp
with a group (or gid) allowed to read the device file (use$(stat -c "%g" /dev/bus/usb)
to get the right group)
- change
- Open
http://127.0.0.1:7123
in your favorite browser
Docker Compose Example
version: "3"
services:
snd:
image: ghcr.io/bigjk/snd:master
ports:
- "7123:7123"
devices:
- "/dev/bus/usb"
group_add:
- uucp
volumes:
- "/some/place/to/persist:/app/userdata"
At the moment Sales & Dungeons only supports the ESC/POS (Epson Standard Code) control codes, which is still one of the most used control code set. Check if a thermal printer you are interested in mentions ESC/POS or Epson in the description or manual.
In general the rule of thumb is:
- Most cheap chinese thermal printer found on Amazon or AliExpress support it
- Most epson thermal printer obviously support it
- A lot of older Serial printer (like Metapace T-1) also support it
More specific information about tested printers can be found in the wiki: Printer-Settings
Templates: Templates are created in HTML (and CSS) in combination with the Nunjucks templating language. You can imagine the templates as little websites. That makes it possible to use all the nice and convenient layout options that HTML and CSS has to offer and even include any common framework you might need (e.g. Fontawesome for Icons).
Rendered HTML: After creating a template you can create entries with the data you want and print them. Nunjucks will create the rendered HTML from the data you want to print.
Rendered Image: Then this HTML get's converted to an image. Currently this conversion is done by Chrome via the Chrome Debug Protocol. Although Chrome seems like a huge overkill for just HTML-To-Image conversion it's the standard solution at the moment because it supports most of the modern HTML and CSS features.
ESC / POS Commands: The last step before our awesome template hits the Printer is the conversion from the rendered image to the "draw image" command of the printer.
Printer: The generated command will then be sent to the printer and printed. Now your template is ready to be used!
